Anandak, a red dragon, has taken over an abandoned dwarven stronghold as his lair. He has also assembled together a rough confederation of monsters to act as his bodyguard. Anandak is preparing to enter into an alliance with the Black Prince, the March Lord Draven. The plan is for Anandak's monster allies to terrorize the lands north and east of Knacker Knob while the Black Prince, on pretext of marching to the aid of Knacker Knob, take control of Knacker Knob and the surrounding region. An emissary from the Black Prince, Lord Gonzaga, is currently in the dungeon, and he is in possession of papers that might reveal the Black Prince's treasonous plot. The lair is horribly overcrowded because monsters of all tribes and gangs are gathered to take counsel with the red dragon. Monsters are sleeping in the hallways because there is so little room, and the antagonism between races is at flash point. The PCs may be able to fan these resentments into intermonster battles. League of the Red Serpent is the third dragon's lair to conquer. Part of TSR 1073 The Dragon's Den

“The Temple Between” is an adventure for 9th level characters, and it is challenging enough to take them to 11th level by the time all is said and done. Although intended as the final chapter of the heroic tier portion of the Scales of War Adventure Path, it can be run as a standalone adventure, or as an adventure in a campaign of your own making, with a small degree of modification. It contains elements of urban investigation, dungeon delving, and even wartime conflict, making it a suitable adventure to players of many tastes and preferences. The western end of Elsir Vale has been greatly troubled in recent days. The threat of the orc hordes from beyond the Stonehome Mountains, though turned back at Bordrin’s Watch, still lingers in the people’s minds. Peculiar and hostile creatures of shadow lurk in the caverns and caves below. Political squabbling grows among the city’s powerful dwarf clans. All this makes the city particularly vulnerable to an enemy nobody saw coming - that nobody even imagined. This enemy has goals and objectives far beyond the ultimately unimportant Elsir Vale, but the first step is the utter subjugation of Overlook. An enemy who, at least in part, is already here. In this adventure the player characters start by investigating the strange behavior of the city's clergy. They swiftly discover hints of a conspiracy worming its way through the city hierarchy - some members are possessed while others have been replaced by dopplegangers. After trailing this conspiracy to its source they discover a portal that leads to an ancient temple in the mountains. Using the portal, the PCs go to the abandoned ancient temple where they must confront both a cadre of fey and a band of mercenaries, from whom they learn there is a plot for a full-scale invasion of the region! The PCs must them rush back to Overlook and cement their place as heroes as they face off against the invading forces. Pgs. 4-71

A great evil force descended on the town of Phlan years ago. The townspeople were all either killed or driven away, and Phlan became (literally) a ghost town. Fifty years later, the survivors are ready to reclaim their town. But they need a band of strong and brave adventurers to lead the fight-they need you. Ruins of Adventure is a set of connected short adventures written by James Ward, David "Zeb" Cook, Steve Winter and Mike Breault-four names familiar to all AD&D game fans. It uses the same setting, locations and characters as the classic computer game Pool of Radiance by Strategic Simulations, Inc. In fact, many of the scenarios here in Ruins of Adventure will provide important clues to the successful completion of Pool of Radiance. TSR 9238

The Underdark is a subterranean wonderland, a vast and twisted labyrinth where fear reigns. It is the home of horrific monsters that have never seen the light of day. It is here that the dark elf Gromph Baenre, Archmage of Menzoberranzan, casts a foul spell meant to ignite a magical energy that suffuses the Underdark and tears open portals to the demonic Abyss. What steps through surprises even him, and from that moment on, the insanity that pervades the Underdark escalates and threatens to shake the Forgotten Realms to its foundations. Stop the madness before it consumes you! Note for DMs: This adventure is not for the faint of hearted, to run or to play. The module starts with 10 NPCs traveling with the party through the grueling Underdark. This number can grow. The encounters within the book are often incredibly deadly for the characters that would be going through it. This is because the module expects them to run or talk their way through the events, or, in some cases, the module expects them to lose. If your players aren't the kind of party to run, talk, or surrender, do not get this adventure. The module almost requires that you use milestone leveling because the experience provided does not commonly get players to the levels they should be once they get to certain milestones in the story (7th when they leave the underdark, 15th when they face the demon lords.) Good luck and happy questing.

From The Magazine: "Every summer, Duke Hightower holds a competition quite different from the traditional jousting and archery tournaments held by similar lords of his station. The rules of his tournament change from year to year, and, to oversee the games, the duke has appointed two wizard brothers who help choose the setting and create the rules and challenges of the competition. This year the competition is called the “Owlbear Run,” an overland race that requires each participating team to escort a live owlbear from the town of Telvorn to the town of Milvorn. The teams will face a variety of challenges; some are devised by the wizards, others by the competing teams or their sponsors, and some occur entirely at random. All of these tests are in addition to the challenges inherent in motivating a temperamental owlbear. Fortune and fame await the first team to cross the finish line, and the local lords sponsoring the race are eager to enlist skilled champions for their causes." Pgs. 2-27
